' To all whom it may concern.

. ducting nozzle therefor to increase'the com- Be it known that I, PAULW. Korrs, a citizen of the United States, residing at Proctor, in thecounty of St. Louis and State of Minnesota, have invented new and usefulImprovements in Burners, of which the following is a specification.

' My present invention has reference to a liquid fuel burner, and myobject is to simplify and improve such class of devices and to produce aburner in which the fuelis heated. in its passage through the coninsugar mills and that may employ molasses as the combustible agent, thesame being heated in its passage through the burner nozzle for theatomlzation or the breaking up of the particles of fuel and havingdireqt'ed thereagainst at'its outlet through the nozzle a fine spray ofsteam which is criss-crossed to insure a better atomization of the fuelfor directing the said fuel from the nozzle into the fire box, theburner, of course, being susce tible for use in connection with otherfue s, such as oil or the like.

With the foregoin broadly stated objects in view and others w ich willpresent themselves as the nature of the invention is better understood,reference is to be had to the lar drawings which accompany and whichformpart of this application.

In the draw1ngs:- e v Figure 1 is a lan view of a burner in accordancewith t is invention.

Figure 2 is an approximately central vertical longitudinal sectiontherethrough.

Figure 3. is. a perspective view of the nozzle.

Figure 4 isa central transverse sectional view through the improvement.

Figure 5 is a perspective view of the nose piece employed. I r

.The heater chamber of the improvement comprises a casting l-havinfi a'central tubupassage 2 .therethroug The 'castmg, has outstandingapertured ugs 3 designed to be secured on a support. The apertured lugspermit the' burner to be properly sup-,

ported and adjusted with respect to the fire,

box in, which the burner is arran ed. The ends of the chamber 1 areforme with interior threads 4. As both ends of the chamber 1 -aresimilarly constructed, it will be apparent that the nozzle and nosemember, hereinafter to be described may be attached to either of saidends.

-One vside of the casting comprising the chamber 1 has a threadedopening there-' through, and screwed in this ening there is a pipeconnected to a suite le source of steam supply, and whereby steam is letinto the chamber. In this connection,'I desire to state that in lieu ofsteam, other vapor-- ized fluids, preferably of a combustible nature,may be employed.

Screwed in, one of the threaded. ends 4 of the chamber 1 there is thethickened and exteriorly threaded portion f the nozzle 7. The nozzle 7,and its portion 6, are round in cross section. portion 6 of the nozzleand designed to contact with one end of the chamber 1 there is a jambnut 7'. By this arrangement, the nozzle may be ad'ustably received inthe chamber 1. Outwar of the threaded enlarged portion 6 of the nozzle7, there is a further enlargement, indicated by the numeral 8, providedwith interior threads for engagement with api e member 9 through whichthe liquid gravity into the burner.

The head of the nozzle is indicated, for distinction, by the numeral 10.The head is provided by thickening the body of the nozzle, and the outerend of the head is cone- Screwed on the threaded el is fed by shaped, asindicated by the numeral 11.

The head, is provided with any desired number of annular depressions 12forming annular. shoulders therebetween; These shoulders are providedwith lon itudinal aligning channels 12. The conica end 11- is formedwith spaced longitudinal channels 11' theinner walls of which arearranged angularly at approximately 20 degrees.

Screwed in-t e outer or free end of the chamber 1 there is the reducedendv rtion of a nose piece 13. o The nosepiece 1 has a rounded bore toreceive the cross sectionally rounded head '10 ofthe nozzle. therein,the

said bore. being inwardly rounded to provide a conical portion'14 thatis disposed adjacent tothe conical end 11 of the head 10. The nose piecehas an inwardly flared mouth 15 which communicates with its bore v andwith the bore of the nozzle. Incident to the threaded engagement of the.nose piece ing, of course, loosened to permit of such adjustment.

Steam or any other suitable heated va-' porized. agent is let in thechamber 1 through the pipe 5. The steam surrounding, the nozzleeffectively heats the same, so that the li uid or semi-liquid fuel whichis directed y gravity through the nozzle willbe heated in its passagetherethrough. This; tendsvto atomize such fuel and increase the]combustibility thereof. The steam finds an-outlet between the bore 14.of the nose piece 13 and the head 10 of the nozzle. The outlet aspreviously inferred, may be-restricted or enlarged- The steam, beforereachin the outlet, will be directed throu h the c nnels 12 into thegrooves 12 an abutting with the walls thereof will be retarded, and 3particles of dirt will be prevented from passing into the flared mouthof the nose piece and this serves toimpart a cries-cross action to thesteam. The steam then passes through the channels 11 as well as aroundthe, conical end of the head .10 so that the same will be'forciblyinjected into the fuel passing through the nozzle to thoroughly mixtherewith, and likewise to direct the fuel through the flared mouth 15of'the-nose piece, causing the same to be forcibly ejected therethrougin a copious spray in all directions into the fire box for filling theentire fire box.

From the foregoing descri tion, when takenin connection with thedrawings, it

will be noted that I have produced a simple burner for liquid fuelswhich'may becheaply manufactured and readily installed. The nose piecemay be arranged on either end of the casing 1, and all of the parts'constituting the improvement are interchangeable so that any damagedparts may;

be readily replaced. I wish to state, however, that I am not to berestricted to the precise structural features herein set forth but maymake such changes therefrom as fall within the scope of what I claim,

Having described the claim A liquid fuel burn'er, com rising a bodyhaving a tubular bore, thre ed at the ends thereof, and having a centralsteam inlet, a liquid fuel conducting nozzle having a thickened; portionwhich is threaded and which is screwed in one end of the body, a

jamb nut screwed in the said thickened portion of-thenozzle andcontacting the end-of the body through which the nozzle enters,

said nozzle having a headed end, whose outer portion is cone-shaped,said head hav-.

ing spaced circumferential grooves and spaced longitudinal passages forintersecting the circumferential grooves, and the cone-shaped head ofthe nozzle having passages aligning with the first mentioned passagesbut which last'mentioned passages are struck at angles of approximately25 de-' grees, and a nose iece screwed in the second end of the b0 y andhaving a bore terminating in a conical end to'receive the head of thenozzle and the conical end thereof therein, and said nose piece havingan inwardly flared month which communicates with its bore and with'thebore of the nozzle; g
